Which types of ATEX codes can be distinguished?

Answer

Whether a lamp is or is not ATEX certified can be seen on the housing of the lamp. This consists of a number of encodings. These codes and what they stand for can be defined as the following:

CE: This code agrees that products meet all quality requirements of the European Union.

Ex: The specific sign for explosion prevention.

G, D or GD: Applicable in gas (G), dust (D) or both (GD) atmospheres.

E Ex: Approved for use in explosive areas according to the latest common European requirements.

E ib: Degree of protection.

IIA, IIB or IIC: The gas group in which the product falls (IIA represents the smallest risk of ignition and IIC represents the largest risk of ignition).

T1 t/m T6: The temperature classification of the bulb that is used. T1 represents the highest temperature and T6 the lowest temperature.

An ATEX certification must be issued by a notified body, such as KEMA or DEMKO. If the lamp is assessed by a non-certified testing institute the zone in which the certification is granted will be a maximum of 2. This is the lowest protection class/zone.
